A flavoprotein; forms, with another flavoprotein ('electron-transferring flavoproteins') and EC 1.5.5.1 electron-transferring-flavoprotein dehydrogenase, a system reducing ubiquinone and other acceptors.

Rate-limiting Description

"Results of RV pressure overload studies in mice transgenic for the promoter region of the gene encoding human medium-chain acyl-CoA dehydrogenase (MCAD, which catalyzes a rate-limiting step in the FAO cycle) fused to a chloramphenicol acetyltransferase reporter confirmed that repression of MCAD gene expression in the hypertrophied ventricle occurred at the transcriptional level."
